Coevolution of Drosophila melanogaster mtDNA and Wolbachia genotypes.

ABSTRACT: Maternally inherited microorganisms can influence the mtDNA pattern of variation in hosts. This influence is driven by selection among symbionts and can cause the frequency of mitochondrial variants in the population to eventually increase or decrease. Wolbachia infection is common and widespread in Drosophila melanogaster populations. We compared genetic variability of D. melanogaster mitotypes with Wolbachia genotypes among isofemale lines associated with different geographic locations and time intervals to study coevolution of the mtDNA and Wolbachia. Phylogenetic analysis of D. melanogaster mtDNA revealed two clades diverged in Africa, each associated with one of the two Wolbachia genotype groups. No evidence of horizontal transmission of Wolbachia between maternal lineages has been fo
